VEHICLE-TIRE.

alipueanon inea April 2a, 1910. serial No. 557,229..

To all whom t may concern Be it known that I, GEORGE E. STARN, a citizen of' the United States, residing at Camden, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Vehicle-Tires, of which the .following is a specification.

My invention relates to pneumatic tires' for vehicle wheels, more particularly for automobiles and other road vehicles.

The object of the inventionv is to provide an eiiicient, .practicable and serviceable pneumatic tire having im roved treading and riding qualities and w ich will be substantially non-puncturable, and one which, in event of loss off air `or deflation of the inner tube, will allow the wheel to travel Without Contact of the rim with the ground,

and hence without dama e to the rim or the 20- tire, and also without lia ility of accidental detachment of the tire from the wheel.

A further object is to provide a construction of 'the tire and rim which will permit easy adjustment of the tire, or detachment and replacing of the same. i

A still further ob-'ect ispto provide'a sim- I ple, inexpensive and. practicable form of manufacture.

The invention will be .hereinafter describedwith reference to the accompanying drawin and thenpointed outy in the'claim ,annexe to this specification.

Said drawing is a cross-sectional view of `a.' vehicle rim and tire embodying my improvements.

In said drawing, 1 denotes the rim which contains and supports the tire, and which is shown bolted to the wooden felly 2 ofl the wheel. The rim, which is preferably made of steel, is substantially ULShaped in' cross section, and comprises abroad channeled ring 3 and side'plates 4, one bf which is fixed 'and the other removable.

The rim, being in the form of a channeled ring, has annular side flanges 5 and the in ner opposed faces of these flanges diverge outward so as to provide extended bracing supports for the inner tube. 'lhe edges of these flanges constitute shoulders or abutments 5 which also form seats or supports. for the tire against the side plates which project radially beyond the flanges "as shown. In the illustration, the fixed side plate is shown as riveted to one flange 5 5 while the -removable side plate is secured inflatable member; the parts ably made as separate elements, the inner to theoppositelange by abolt t5 and nut 6*.' It will be readily appreciated that this con- Patentea Aug. 13,1912.'v

struction, together with the form of the rim,

facilitates the assembling and disassembling oa. the parts and thatl when the reinovable side `plate is detached to permit repairing, the inner tube will be held by the channeled ri-ng until the operators hands are free. `The liability of injury to the inner tube from accidental Contact with sharp 615 tools or from other sources -is thus reduced to a minimum. l

The tire, contained within and embraced laterally between the side lates of the rim,

comprises an inner infiata le' portionor tu- 70 hula-r meinlber i', and an outer broad, solid tread. portion or cap-like member 8 which overlies and is yieldingly sup orte'cl by the ing prefer' inliatable member being of rubber, and the .outer solid tread-member being made preferably otfiber though it also may be made off rubber. Both members are in effectI clamped between the side plates 4 of the'80.

rini, which extend considerably beyondl the crown of the inner member and hold the cap-like outer tread member in place. The.

tread member 8 has a concave base or inner side and is seated upon a convex crown of 8 5 the inner tube or inflatable member 7; and the latter, having approximately the form of a trapezoid in cross section, fits within the channeled ring 3 and is formed on its outer sides with annular projectionsl 7 90 5g which rest upo'i'i the annular shoulders 5 and thereby support the inner/.tube or' iniatable member all the way around the rim;

the inflatable or tubular inner member being so-shaped in its construction as' to con- 95 'abut-ments ati'orded by the flanges 5, to

which the air tubev is molded to conform,

tion and prevent the outer shoe or cap-like tread member from sinking into the rim far enough to allow the latter to contact with the ground; so that," in event of accident. to

or leakage of the air chamber, an automobile 11 will hold the inner member in proper posi- 10,

At the same time, should 1 0 intl-miie. und

irre', having e. broad nolrpuneturuble tread 'equipped with my tires is permitted to proceed without delay for repairs and Without to the vehicle., for the tread Will always Contact with he ground and the rim never will. Furhermore, the retreat of the iread portion of the tire'ino the rim at the loweigeide of the wheel will never be sulicient ',o permit the tread to slip out al; rhe' upper `side or the Wheel, for the lianges 5 form e positive stop or abutment which liniizs the einking o the tread to e distance less eben i'mi'; beween Vhe inflatable member and 'l'l'ie eurer edges of 4theside plaies el.

The ire constructed in "tiro parts as illusxeied Will, when .inllaleCh'eonsiitute to all purposes u practically integral overlying e eorrespondiiigly breed aireliamber, the form o" which in. conjunction .with the eoneeve hase ihe tread, land shape of the rim supper-ring the air ehzmr ber, produces e, if'ery eleient and sprngy cushion ire, 'pronoring the Comfort', of the .o'czupenie of the vehicle and relieving the flel'er from ,ibrel'ion; While h'e breadth of ,in-e ireml lends to prevent slnddlng and con 'ribuiefs te the even running of the machine.

The air chamber being incased within the rim and under bhe treed is protected from pueenre and not liable io rupture.
